Abstract (en)
A processor system includes: a main processor part(1) including a decoder(7) for decoding an instruction, a register part(8) for storing data therein and for outputting data stored at an address included in the decoded instruction, a first memory(12) for storing data therein, and an operation part(10) for making an operation on the basis of the decoded instruction using data outputted from the register part and for storing the operated result in the register part or the first memory; and a coprocessor part(20) including a control register(21) for storing therein a value of a control signal, an address generating part(23,24,27), a memory part(25,26,28) provided so as to correspond to the address generating part, and a main controller(22) for feeding a command signal to the address generating part on the basis of the value of the control signal stored in the control register, to cause the address generating part to generate an address, for causing the memory part to output data stored in the generated data, and for feeding the outputted data to the operation part of the main processor part to cause the operation part to make an operation. Thereby, the proposed processor system can carry out a high speed processing and wherein the whole occupied area is smaller. <IMAGE>
